Technology: breaking the hegemony that monopolizes the world

"So when will our battery technology be officially commercialized? Biati has already commercialized sodium batteries, and has used lithium iron phosphate technology to the third generation.

The Ningde era is also betting on the price of lithium mines, wanting to firmly occupy the majority of the share of new energy batteries, and prevent BYATT from continuing to advance.

Never mind Tesla's garbage 4680 batteries, they can only hang around with old and out-of-date technology.

Now Neon car companies have been oppressed by domestic car companies to reduce the price of all products by more than 20%, which has not stopped the downward trend. The sales of Nissan and other brands have even been cut in half last year.

This year is the best window period and the most important milestone window period. We must provide more technologies to partner companies, otherwise they will start to force us.

You know, at present, a small car series of Biati can reach the highest monthly export of 1,000 vehicles, and the domestic monthly sales exceed 40,000.

After several years of shuffling and selection, these partner manufacturers have formed a two-way lane for self-research and acceptance of our authorized technology. If we are not faster than them, we will be abandoned! "

Um? ? ?

In the last second, I was still talking about astronomy and human accidents.

Urging product technology in the next second?

Are you one of those demand managers? Or project leader?

The young researchers and assistants who had just entered the Titan star department for a few years were stunned, and they hadn't turned their heads yet.

And those project leaders, whether they are project leaders related to new energy, or project leaders who have nothing to do with new energy and new energy vehicles, all held their breath at this time, and some even held their breath. He also shrank his neck, trying to minimize his sense of existence.

During this period of time, everyone was stimulated by the previous projects such as AI girlfriend, bionic robot, and mecha to focus on the integration of existing technologies, so there was a lack of energy allocated to the basic materials and system development of their own projects. .

If there is no substantial progress in such a short period of time in other companies, everyone can pat their chests and say: "This is a normal phenomenon in scientific research. The positioning of each screw needs to consider issues such as structure and material rigidity, so we don't have that yet. This is called a milestone progress, but according to the plan, with some of the results we have achieved so far, we can still complete the task."

But at Kyushu Technology, facing the fierce man on stage who dared to call Xia Wei, Rice, and other executives of mobile phone manufacturers to come to Rongcheng to "give money" when the company had no formal research team in the early days of its business, even if it was seniority No matter how young the researcher was, he also consciously shut his mouth.

But Gu Qing didn't stop and wait for these young people to turn the corner.

He continued: "The outbreak of solar flares and climate change will make human beings rely more on technological products to improve and help production and life.

Under the condition that the physiological needs are not met, as long as our products have irreplaceable particularity, the previous measures for closing the shutters will become window paper, which will be broken with a light touch.

So we don't have enough time. "

Everyone's eyes were a little erratic, embarrassed, and dull.

But it only lasted for a few seconds, and an upright man in science and technology raised his hand as if he didn't know what it meant to lose face.

"Zhou Wu? I remember that you are in charge of polymer materials. What do you say?"

For this guy from Harbin Institute of Technology, who is a classmate with Chu Ci and others, but has always been practical in his field of expertise, and has never done research in cross-fields, Gu Qing is very fond of...

Not impressed.

And the reason why the other party was able to become a small management research management team was only because of being down-to-earth, and it was one of the personnel changes that Xuanwu and Xiezhi made when they adjusted the research team together.

After getting Gu Qing's permission, Zhou Wu stood up shyly like a college student who has not yet graduated, and then saw that the microphone on the table had turned on the green light for radio, and then hurriedly took the microphone to his own lips.

Most of the people sitting here knew that this microphone can be perfectly picked up without having to bring it to the mouth, but no one laughed at this young man.

"Our research team discovered a carbon crystal that can change its structure through energy impact, but the composition of the substance is very harsh. At the same time, a few months ago, a Dr. Da Xia who worked in Uncle Sam described it in a Nature paper , he and his collaborators discovered a macroscopic layered crystal that is charge-neutral and purely carbon-based.

Although this two-dimensional molecular sheet is similar to graphene, it is a layered two-dimensional material composed of covalently bonded fullerenes as structural units. In appearance, it presents a hexagonal arrangement.

This result is very similar to our findings, but according to his description, they discovered it by mechanical exfoliation, and also said that these crystals can produce neutral carbon two-dimensional molecular sheets with clean interfaces, This caused conflict among our entire experimental group.

The previous steps of our double-shot are roughly the same, that is, to create single crystals of fullerene layered polymers by dilute acid treatment of fullerene alkaline earth metal complexes grown by chemical vapor transport, which can preserve the original structure. At the same time, the intercalated alkaline earth metals can be removed to form a mechanically exfoliated, charge-neutral two-dimensional covalent fullerene network.

Compared with those previously discovered polymeric fullerene species, the thermal conductivity of this material is nearly an order of magnitude higher than that of molecular fullerene crystals, and this high-quality charge-neutral all-carbon macroscopic crystal can be processed to obtain no reflection on the surface. 2D sheets of ions or contaminants, thus meeting the requirements for creating high-quality heterostructures and optoelectronic devices.

When we discovered this material, it was on April 1st, when solar flares erupted. Now it seems that there should be a very slight fluctuation in our experimental equipment, resulting in an extremely small difference in the energy impact. This new carbon material that led to our discovery has the same properties as the doctor claimed, but it is not replicable. "

Gu Qing didn't interrupt Zhou Wu's stumbling speech, he listened seriously.

"So our group has been trying to replicate the success of this material during this time, but even when the solar flare erupted again a few hours ago, we hurriedly repeated the steps of the last success, but still got nothing.

So I suspect that our research equipment needs a major overhaul. At the same time, some high-tech equipment may need to be replaced. "
